Garage Door Opener Closes Then Opens On Its Own

Button button the spruce.

Garage door opener closes then opens on its own. A garage door that randomly opens by itself is not a common problem but does occur from time to time. If this is a sears srt without external travel limit switches the internal travel limit is out of adjustment telling the opener to continue after the bottom of the door makes contact with the garage floor basically driving it into the ground until the force required exceeds what the safety system force is set at. Likely culprits include the wires the internal circuitry and more. Garage door openers operate on one of many frequencies and while it is possible for one of your neighbors remotes to open your garage door it is highly unlikely.

If your garage door is closing fully and then reversing to open again then it may be due to a problem with the close limit switch. Reverses on its own if the garage door only travels down an inch or so before reversing something is probably blocking the beam between the two safety sensors at the bottom of the rails or the sensors aren t aligned. Opens and closes by itself when your garage door opens or closes when you haven t triggered the remote one possible cause is that a neighbor s remote was programmed at the same time as yours.

A garage door opener operating on its own may be caused by several problems. This brain can wear out in time so you could need a replacement. When the garage door opens about halfway or 5 feet from the ground and stops the up limit switch needs to be adjusted. Erase all codes in your remote and then reprogram it.

Your garage door s logic board is the brain of your garage door opener. This is done with the help of sensors in the motor and on each side of the opening near the floor and mounted on the tracks. In order to fix this you ll want to make small changes to the close limit setting until the door opener knows to stop once the door has reached the floor. When the logic board wears out it can cause your garage door to close then open and vice versa without explanation.

Newer openers operate on rolling codes making it almost impossible for this to happen. Open the garage door and watch it closely as it opens. In garage door operators made after 1993 there are required safety features that open the door during the close cycle when they detect something blocking the door.
